Builders use hollow concrete blocks to construct walls, floors and other structural surfaces both inside and outside a home. They are also used to construct footers and foundations to support a building and evenly distribute the load of the building. Most hollow concrete block structures are built using mortar, and many also require steel reinforcement to add strength and support.Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years. Our main products are as follows:concrete pump,mini concrete pump,etc. We will provide you with the best product and service. Benefits: Like all concrete products, hollow concrete blocks are known for their strength, sturdiness and durability. Structures built from these blocks are virtually soundproof and are highly resistant to termites and other pests. Concrete blocks offer a high level of wind resistance and are able to withstand harsh weather and a wide range of temperatures. Because they are hollow inside mobile block machine, these blocks also offer a high strength-to-weight ratio, which can reduce overall building loads compared to solid blocks or stone. Drawbacks: Many concrete products are considered unattractive and are not typically used as a finish material. While they can be painted to improve their look, concrete blocks are often hidden beneath other, more attractive finish materials. They are also relatively cold if left insinuated and have none of the natural insulating properties of wood or brick. Finally, concrete blocks are heavier than wood framing, which could increase overall structural loads
